Home automation is the residential extension of building automation.
It is automation of the home, housework or household activity.

Fellow Italian here. I've also looked for this to disconnect a cheap EV car charger from the mains (disconnecting only one pole always results in the lifesave breaker to activate). I couldn't find any. The only solution, I think, is to use a sonoff or a shelly to drive a two pole relay.
Don't have a solution for you. Might be quite big and bulky with two relays in it where 99% of people might not need such devices.
There are some products out there for switching live+neutral at the same time, for example norway requires it in areas where there is risk of water, like bathrooms and kitchen (close to the sink) because some part of norway have two off phase live wires instead of live+neutral.
I have never seen plugs, but I've seen puck dimmers and relays certified for switching neutral+live in norwegan wet areas. If you want to build on such a puck.
If your switch is connected to the socket and disconnects the 'hot' side from the socket, it doesn't matter if they turn the plug around, there is still no 'hot' at the socket.
Yes that is true, but I am pretty sure if the socket got pulled out in some way it would end up in the wrong position. That and the switch for toggling it might be in an inconvenient position.
